Pneumococcal Capsular Polysaccharide Structure Predicts Serotype Prevalence
There are 91 known capsular serotypes of Streptococcus pneumoniae. The nasopharyngeal carriage prevalence of particular serotypes is relatively stable worldwide, but the host and bacterial factors that maintain these patterns are poorly understood. Given the possibility of serotype replacement following vaccination against seven clinically important serotypes, it is increasingly important to un...
متن کاملPneumococcal Capsular Polysaccharide Vaccine
Streptococcus pneumoniae (pneumococcus [Pnc]) is a common bacterial agent found in mild mucosal as well as severe systemic infections. Local infections, such as acute otitis media, are rather common; every child has at least one during the first 2 years of life (1), and Pnc is the causative agent in approximately half of the bacterial culturepositive cases (2). Pneumonia is another disease ofte...
متن کاملPrimary structure of the Escherichia coli serotype K30 capsular polysaccharide.
Methylation, 1H nuclear magnetic resonance, and bacteriophage degradation results indicate that the Escherichia coli serotype K30 capsular polysaccharide consists of leads to 2)-alpha-D-Manp-(1 leads to 3)-beta-D-Galp-(1 leads to chains carrying beta-D-GlcUAp-(1 leads to 3)-alpha-D-Galp-(1 leads to branches at position 3 of the mannoses.
متن کاملAvidity, potency, and cross-reactivity of monoclonal antibodies to pneumococcal capsular polysaccharide serotype 6B.
Many pneumococcal capsular polysaccharides (PSs) are similar in structure, and a pneumococcal antibody often binds to all of the PSs with a similar structure. Yet, these cross-reactive antibodies may bind to the structurally related pneumococcal capsular PSs with an avidity too low to be effective. If memory B cells producing such weakly cross-reactive antibodies are elicited with pneumococcal ...
متن کاملCapsular polysaccharide synthesis regions in Klebsiella pneumoniae serotype K57 and a new capsular serotype.
Community-acquired pyogenic liver abscess caused by Klebsiella pneumoniae is an emerging infectious disease. We explored the capsular polysaccharide synthesis (cps) regions of three non-K1, non-K2 K. pneumoniae strains, A1142, A7754, and A1517, from Taiwanese patients experiencing pyogenic liver abscess. Two of the strains, A1142 and A7754, belonged to capsular serotype K57, while the third bel...
